To enable bash completion on Ubuntu 14 make sure you have bash-completion installed:
apt-get install bash-completion
If so open /etc/bash.bashrc:
vim /etc/bash.bashrc
Then comment out the following lines:
# enable bash completion in interactive shells if ! shopt -oq posix; then if [ -f /usr/share/bash-completion/bash_completion ]; then . /usr/share/bash-completion/bash_completion elif [ -f /etc/bash_completion ]; then . /etc/bash_completion fi fi
And restart you bash:
exec $SHELL
